FEED-TABLE FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 614,326, dated November15, 1898.

Application filed June 12, 1897. Renewed September 9 serial 1 (1%11105910 To all whom it may concern.-

Be it known that I, SIGMUND V. HUBER,a citizen of the United States,residing at Youngstown, in the county of Mahoning and State of Ohio,have invented or discovered certain new and useful Improvements inFeed-Tables for Rolling-Mills, of which improvements the following is aspecification.

The invention described herein relates to certainimprovements inmechanism for shifting and axially rotating ingots, slabs, 620., duringthe process of rolling, and has for its object aconstruction andarrangement of mechanical devices whereby an ingot, slab, (he, may bemoved laterally on the feed-table of a rolling-mill and whereby theslabs may be turned and held on their edges while being fed into therolls.

In general terms the invention consists in the construction andcombination substantially as more fully hereinafter described andclaimed.

In the accompanying drawings, forming a part of this specification,Figure l is a side elevation of my improved manipulating mechanism. Fig.2 isatop plan view of the same, showing its position in relation to thefeedtable. Fig. 3 is' a sectional elevation, the plane of section beingindicated by the line III III, Fig. 2. Figs. 4 and 5 are detail views ofthe mechanism for axially rotating and shifting a slab, the severalparts employed in such operation being shown in the positions which theywill occupy at the beginning and end of the operation.

In the practice of my invention I employa truck consisting of a frameformed of I-beams 1, supported on wheels 2, which are adapted to movealong rails 3, so arranged that the truck will move transversely of thefeed-table. The truck is moved by means of fluidpressure cylinders 4,preferably of the singleacting type, and arranged at opposite ends ofthe truck and having their plungers 5 connected to the truck, as clearlyshown in Figs. 1 and 2. As shown in Fig. 3, the truck is provided withsuitable guides 6 for the truck portion 7 of the frame 7, to which aresecured the posts or standards 8, projecting up between the rollers 9 ofthe feed-table. The upper ends of the posts or standards 8 arepreferably provided with prongs or fingers l0 10,

which are preferably formed with spurs, so as take a firm engagement onthe ingot or slab to be shifted. As shown in Figs. 1 and 3, the frame 7,carrying the posts or standards, is connected by links 11 to the arms12, which are secured on a shaft 13. This shaft has also secured theretoan arm let, connected by a link 15 to the piston-rod 16 of thefluidpressure cylinder 17, which is mounted upon suitable supports uponthe truck. This cylinder is connected to an expansion-coupling,consisting of the pipe 18, which projects or extends into the tube 19,mounted on standards 20, secured upon a suitable foundation. One end ofthe pipe 18 is secured upon the truck and is connected to the cylinder17, while the opposite end thereof extends into the tube 19, which inturn is connected to a suitable source of fluid-supply. It will bereadily understood by those skilled in the art that an ingot or slabresting upon the feedrollers 9 of the table can be shifted along thefeed-rollers by raising the posts or standards 8 and then shifting thetruck back and forth, as required. An axial rotation of the ingot orslab can be effected by shifting the truck until one of its prongs orfingers 10 or 10* is under one edge of the billet or slab and thenforcing the post or standard 8 upward.

While an axial rotation of the billet or slab can be effected in themanner described, it is evident that the prongs or fingers 10 or 10 willnot turn the slab onto its edge nor hold the slab in such position whileit is being fed into the rolls. In order to produce and maintain thisedging position of a slab, a series of arms are so mounted with relationto the standards or posts 8 as to be capable by an up-and-down movementof completing the axial movement of the slab onto its edge and by ahorizontal movement, if necessary,shifting the slab laterally againstthe sides of the prongs or fingers. A convenient means for thus turningand holdinga slab in an edging position consists of a series of bentarms 21, pivotally mounted on bars 22, which in turn are adapted to moveback and forth in guides 23, preferably formed in the side bars 24 ofthe feed-table. These bars 22 are connected at one end by links 25 toarms 26, which have their lower ends secured to a shaft 27, as clearlyshown in Figs. 1 and 2. One of these arms 26 is connected at a pointintermediate of its ends by links 28 to a plunger 29 of thefluid-pressure cylinders 30. By the admission of fluid-pressure intothese cylinders the slide-bars 22 may be shifted back and forth, asrequired. As clearly shown in Figs. 1, 4, and 5, the arms 21 are sopivoted upon the slide-bars 22 that one end thereof may be turned up toa vertical position, projecting above the feed-roller 9 of the table.The opposite ends of these arms are connected by rods 31 to the lowerends of arms 32, having their opposite ends secured on a shaft 33, whichis mounted in suitable bearings in the slide-bars 22. One of these arms32 is connected by a link 34 to the plunger 35 of the fluid-pressurecylinders 36, which are secured to the slide-bars 22, as clearly shownin Figs. 1 and 2. These cylinders are connected by pipes 37 and 38,having flexible joints, to a suitable source of fluid under pressure, asclearly shown in Fig. 2 and indicated by dotted lines in Fig. 1. Inoperating this rotating device the posts or standards 8 are so shiftedby the truck that when raised one edge of the slab will drop in betweenthe fingers 10 10, as shown in Fig. 4. Fluid-pressure is then admittedto cylinders 30, so as to shift the slide-bars 22 to bring the turningarms into proper position. Fluid-pressure is then admitted into thecylinders 36, thereby moving the free end of the arms 21 up, so as toturn the slab onto its edge and clamp it against one of the fingers, as10, as clearly shown in Fig. 5. Then by the admission of fluid-pressureinto the truck-cylinders 4. and also into the cylinders 30 the slab maybe shifted along the feed-table, so as to bring it into line with theproper feed-pass of the rolls. As

shown in Figs. 4 and 5, an initial axial rotation is effected by theprongs or fingers 10. Such initial operation is not, however, necessary,as the posts or standards can be raised to one side of the slab, whichcan then be turned on edge against the outside wall of the post orstandard. If desired, an ingot, slab, &c., may be shifted laterally onthe table by means of the arms 21. In effecting such an operation thebars 22 are first moved to such position that the arms 21 will whenturned to vertical. position project up on the proper side of the ingot.The arms 21 are then turned to vertical position, and the bars 22 areshifted by their cylinders 30.

While the mechanism described and shown is considered to be a mosteffective embodiment of my invention, I do notlimit myself to suchparticular construction, as many changes in the relative arrangement andconstruction of the parts directly operative on the ingot or slab orother article and also of the mechanism for operating such parts willreadily suggest themselves to those skilled in the art.

I claim herein as my invention-- 1. In a rolling-mill the combination ofthe feed-table, vertically and laterally movable posts or standards andarms movable up and down and horizontally, the posts or standards andarms'constructed and arranged so as to turn and hold the billet in itsturn ed position, substantially as set forth.

2. In a rolling-mill the combination of the feed-table, a truck movabletransversely of the table, vertical movable posts or arms mounted on thetruck, bars movable transversely of the table and arms movably mountedon said bars, substantially as set forth.

3. In a rolling-mill, the combination of a feed-table, bars movabletransversely of the table, arms movably mounted on said bars andmechanism movable with the bars for shifting the arms, substantially asset forth.

I11 testimony whereof I have hereunto set my hand.
